The design of the above mentioned a new type of street lamp system, can solve peoples needs. The design includes hardware system design and software system design.The hardware system includes the single chip of AT89S52, the clock chip 1302, Analog-to-Digital Converter and photosensitive resistor .The software system is based on Keil, Proteus and other software as the carrier, the use of C language to write the program.Single-chip according to the photosensitive resistor and infrared pyroelectric sensor on the roadside detection and clock chip DS1302 set the time to control the A / D conversion chip to achieve automatic adjustment of LED street light brightness. Through the LCD display time and light sensitivity, through the photosensitive resistor to achieve fault detection, when the street lights break down, the buzzer will automatically alarm. Through the simulation and production, debugging, verify the feasibility of the design content, to further research and development to provide a certain data reference.
